    Quality - Quality - Quality

    Can not be said enough the quality that Riffraff has put into these parts. Going the extra mile with the oring and not the RTV just puts it over the top.

    Top Notch

    Great design and engineering. The craftsmanship of these is evident when you hold them. O-ring is far superior to the factory RTV, and way easier to install. 10/10

    02 intake plenums

    Machining is top notch, anodizing is clean.
    Installation is pretty straight forward o-ring can be a little frustrating a little rtv on the radius’s is helpful. The worst part of it all is that you have to cover them.

    Excelent product

    Posted by Kevin wilson on Nov 1st 2020

    This is an amazing product, clamp better and had a o-ring gasket so you don't need to form a liquid gasket. Keep in mind the install can be tricky the passanget side bolt that gets deleted will not be able to be removed prior to install without removing the hpop housing. Or you do what I did and cut the head off the bolt and all is good.

    Awesome and strong

    Posted by Andrew on Aug 12th 2020

    Wow, these are pieces are engineering. The red almost looks like a candy finish, and I can' t believe how well they are made. Stout, and made in the US, what more could you want. Even came with quality stainless steel hardware.

    The quality of this product is second to none! I am surprised that ever supplier of products for the 7.3 power stroke doesn’t have their own version of this amazing Product. I have purchased several things from RiffRaff for my 7.3 and highly recommended them for superior products, fast service, and quick response to any questions you may have. Clay and his team are fantastic and renew my faith in the commitment to customer service and products made in the USA.
